Aswill be explained more, fully, hereinafter, this ad; vantage, isachieved by offsetting the curve offth'e gnardc. froml that of the lspring to substantially eliminate anyiangleinvwhichithe hair may catch.

It ,is-,a further object of the invention toprovide'means whereby asingle screw connects the winding, arm tothe, handle and connects thehandleto the mandrel in one operation;

The improved, curler comprises a forming bar or" mandrel 5; which,-solely for reduction in weight, is desirably madewith a cavity at 6.Externally; thebar isentirely cylindricalexcept for an annular-channelat I which receives: a screw 8 forrrotatively positioning-the knobs-onthe cIQSedendpfthebar; It will be noted that the knob 9 'has-a-- radialbore-I B i which is sbigger than the threaded shank of screw 8 -1 and iscounterbored at-lI to receive the head' of; the screw: The knobhas-asocket at -12 forxthexend of themandrel and F a recess: I3 as bestSh0W1L'iIl Fig: 3 which is arcuateandopensintothe socket l2 and receivesthe end of the. spring 1armr: I5.

Without the guard member- 24, looks and strands of hair other: thanthose upon which the curler is operating tend to become entangled withthe forming lever-I Sonwiththe 'lockrof hair engaged-:by such lever;with the result. thatthe rotative-movement ofithe former and knohisarrested, and "pain may be caused to the patient.

Icclaimrz l'zlAvhairycurlercomprising a mandrel anda part.- providedwith a -,=rotatablc, mountin on said mandreliand integrally includingags pring arm portion and a guard portion, each of saidportions beingreversely bent upon itself, the reverse bend of the guard portion beingofiset longitudinally of the mandrel beyond the reverse bend of thespring arm portion, and said guard portion including a terminal partextending back over the spring arm portion in partial lapping relationthereto.

2. As a new article of manufacture, a onepiece spring arm and guard fora hair curler comprising a strip having a longitudinally extendingtongue struck from a portion of the strip intermediate its sides andends, side portions of said strip being reversely bent upon themselvesat the base of the tongue and the said tongue continuing beyond thereverse bend of said side portions and having a reverse bend of its ownat a point offset from the bend of said side portions, and furtherhaving a terminal portion extending longitudinally of the strip inspaced relation to the side portions thereof.

3. The device of claim 2 in which the reverse bend of the tongue is oflarger radius than the reverse bend of said side portions.

4. As a new article of manufacture, a combinationspring arm and guardmember for use in a hair curler, said member comprising a strip having asubstantially rectilinear portion and having beyond said portion anelongated slot intermediate its side portions and ends, each of saidside portions being provided with a reverse bend at one end of said slotand thence extending in substantial parallelism and in spaced relationto the substantially rectilinear portion of the strip, said strip havingan integral tongue extending from its said rectilinear portionat one endof the slot beyond said bends, said tongue being provided with a reversebend and a terminal guard portion spaced outwardly from the rectilinearportion and side portions of said strip and extending longitudinally ofthe strip in a rearward direction from the reverse bend of said tongue.

5. The device of claim 4 in combination with a mandrel along which saidstrip extends and a knob rotatable upon the mandrel and provided with ascrew connecting the knob with said strip for the rotation of its saidrectilinear portion about the mandrel, the said strip having a terminalwith a tapped opening in which said screw is threaded. v

'7. A hair curling device comprising a mandrel, a collar memberrotatably mounted at one end of the mandrel, a winding member fixed tothe collar member, said winding me r Comprising an arm member secured atone end to the collar member and extending parallel to the mandrel andreversely bent at its free end to provide a guard member, the said armmember being provided intermediate its ends with a spring clip memberintegral at one end with the arm member at a point adjacent the guardmember and extending in parallel and spaced relation to the arm memberto provide a hair receiving opening, the free end portion of the springclip member being provided with a reversely curved offset portion whichresiliently engages the arm member whereby a tress of hair may beremovably received between the arm and clip members.

8. In a hair curler of the character described comprising incombination, an elongated generally circular in cross section barrel, agroove in said barrel around the circumference and near one end thereof,a relatively short sleeve rotatably mounted on the barrel and extendingover said groove, a tuft of hair engaging member comprising an elongatedthin flat member having spring characteristics andextending to within ashort distance of the other end of the barrel and lying parallel to andsubstantially on the barrel, said collar having a keyway with a depthand width adapted to snugly receive one end of said hair engagingmember, a hole in said collar in alignment with said keyway, a hole inone end of said hair engaging member in alignment with the hole in thecollar, a pin adapted to be held tightly in the hole in the collar andextending through the hole in said engaging means and into said groove,said engaging member comprising a single strip of fiat material andlying generally longitudinally in contact with the barrel and extendingto within a short distance from the other end of the barrel, theremainder of the strip being split into two elements, an end'of oneelement being out free at one end a distance from the free end of thestrip and being curved outwardly at its other end and toward the end ofthe strip, the other element being curved at a'smaller radius andextended parallel to the base for a distance toward said collar and thenbeing curved for contact with the base member. forming an opening andthen being extended outwardly at an acute angle forming an entrance wayinto said opening, whereby the tuft of hair may be inserted into saidopening and wound around the barrel until all of the tuft of hair isformed into a curl and positioned under said base member.

9. As a new article of manufacture, a onepiece spring arm and guard fora hair curler comprising a strip having a longitudinally extendingtongue struck from a portion of the strip intermediate its sides andends, side portions of said strip being reversely bent upon themselvesat the base of the tongue and the said tongue continuing beyond thereverse bend of said side portions and having a reverse bend of its ownat a point offset from the bend of said side portions.
